Description

Information recording apparatus, information recording apparatus control method, and program thereof

The present invention relates to an information recording device that is mounted on a vehicle and used for the purpose of preventing drunk driving, a control method for the information recording device, and a program thereof.

Conventionally, a drunk driving prevention concept car that detects a driver's drinking state and determines that there is a possibility of drunk driving has been proposed (for example, Non-Patent Document 1). . The non-patent document 1 describes the following detection and alarm methods.
The first is a method of detecting alcohol with a sensor. In this method, alcohol contained in the sweat of the palm that touched the shift lever is detected by an alcohol odor sensor built into the shift lever. If alcohol is detected, a warning is displayed to the driver by voice and display on the car navigation screen. And shift-lock at the same time.
The second is a method for detecting the driver state from the face image. In this method, the driver's face is monitored by a camera installed in the meter, and the arousal level is estimated. When it is determined that there is a possibility of drunk driving such as a dozing state, the driver is warned and the seat belt is rolled up by voice and display on the car navigation screen.
The third is a method of detecting the driver state from the vehicle behavior. In this method, the driving behavior of the vehicle is detected, the driving state of the driver such as snoozing and looking aside is evaluated, and if it is determined that there is a possibility of drunk driving, the driver is displayed by voice and display on the car navigation screen. The seat belt is rolled up.

On the other hand, there has been proposed an apparatus for recording necessary information in order to determine whether or not the person was drunk when an accident occurred. For example, Patent Document 1 describes a system that applies a car insurance guarantee when a vehicle has an accident on condition that a safety device mounted on the vehicle is operable. . In addition, it is described that information on the presence or absence of drinking is acquired and recorded in the safety device as information on the driver.

However, if the drunk driving prevention concept car described in Non-Patent Document 1 determines that there is a possibility of drunk driving, it only alerts the driver or shift-locks, so if an accident actually occurs In addition, third parties such as police and insurance companies cannot accurately determine the driver's drinking level at the time of the accident. Further, the method of detecting the driver state from the face image and the method of detecting the driver state from the vehicle behavior have a problem that the reliability of the detection result is poor.
Further, the safety device described in Patent Document 1 only has a description that “acquires information on the presence or absence of drinking and records it in the safety device”, and does not disclose a specific detection method. As a method for detecting the presence or absence of drinking, it is common to use an alcohol odor sensor as described in Non-Patent Document 1 above, but if an accident actually occurs simply by recording the detection result In addition, it cannot be proved that the driver was drunk. This is because there is a possibility that the alcohol odor sensor disposed in the driver's seat may detect the alcohol concentration contained in the passenger's breath even when the driver is not actually drinking.

In view of such a problem, the present invention can provide useful evidence for a third party such as the police or an insurance company to prove that the driver was drunk at the time of the accident.

[First Embodiment]
Hereinafter, an information recording apparatus, an information recording apparatus control method, and a program therefor according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a system configuration diagram of an insurance contract processing system SY to which an information recording apparatus of the present invention is applied. In this insurance contract processing system SY, the information recording device of the present invention is applied in a form incorporated in the navigation device 10.

As shown in the figure, an insurance contract processing system SY includes a navigation device 10, a vehicle 1 to which the navigation device 10 is attached, a driver 100 that drives the vehicle 1, and a car insurance company 200 that handles optional car insurance. And a navigation maker 300 that supplies the navigation device 10. The car insurance company 200 and the navigation maker 300 have a business contract in advance so that the insurance premium is preferentially provided by the installation of the navigation device 10.

When the driver 100 purchases the navigation device 10 sold by the navigation maker 300, the driver 100 declares the device ID (device identification information) of the navigation device 10 in the insurance contract with the car insurance company 200, thereby reducing the insurance premium. You can receive preferential treatment. Further, in the insurance contract, it is necessary to report the vehicle verification information (vehicle number etc.) of the vehicle 1 to the car insurance company 200 as well as a general insurance contract.

On the other hand, when using the navigation device 10, the driver 100 needs to register the vehicle body number (vehicle identification information) of the vehicle 1 in the navigation device 10. The navigation device 10 can be equipped with a memory M with an encryption key (hereinafter referred to as “memory M”, a recording medium). Information) is encrypted and recorded. The vehicle body number and the device ID of the navigation device 10 are also encrypted and recorded in the memory M together with the drinking information. When the vehicle 1 has an accident, the driver 100 removes the memory M from the navigation device 10 and sends it to the car insurance company 200, or reads the data from the memory M using a personal computer or the like, and Send by email. The car insurance company 200 analyzes the memory M, determines the drinking state of the driver 100 at the time of the accident, and determines the application of the guarantee. The analysis result of the memory M is used as evidence by the police etc. for investigation of the cause of the accident.

Next, the functional configuration of the navigation device 10 will be described with reference to FIG. The navigation device 10 includes a detection unit 11, a GPS (Global Positioning System) receiver 12, a map information database 13, a memory M, an operation unit 15, a display 16, and a control unit 20 as main functional configurations.

The detection unit 11 includes a circuit that detects an alcohol concentration (alcohol concentration in breath) by a plurality of alcohol sensors AS1 to AS4 arranged inside the vehicle 1. The detection by the detection unit 11 is periodically executed while the vehicle 1 is traveling. The plurality of alcohol sensors AS1 to AS4 are arranged one by one in each seat and detect the alcohol concentration of the passenger sitting in each seat. In the present embodiment, a four-seater passenger car is assumed, and the detection unit 11 includes four of a driver seat alcohol sensor AS1, a passenger seat alcohol sensor AS2, a rear right seat alcohol sensor AS3, and a rear left seat alcohol sensor AS4. It is assumed to be constituted by two alcohol sensors AS. Each alcohol sensor AS1 to AS4 is preferably arranged in the vicinity of each passenger's head so as to accurately detect the expiration of the passenger sitting in each seat.

The GPS receiver 12 receives position information (latitude, longitude, altitude) and date / time information of the vehicle 1 from a GPS satellite (not shown). The map information database 13 stores map information necessary for the navigation device 10 to specify the current position and perform route guidance.

The memory M is for recording drinking information based on the detection result of the detection unit 11 as described above. The memory M is attached for a period corresponding to an insurance contract period (for example, one year) to prove that the driver 100 was drunk or not drunk when the accident occurred. Used. Accordingly, all the information during the insurance contract period has a recordable capacity. The medium of the memory M may be either rewritable or non-rewritable. The former recording medium can be reused depending on the format, and resource saving can be achieved. In addition, since the latter recording medium can prevent unauthorized rewriting of information, the credibility as evidence when a traffic accident occurs can be improved. When the insurance contract period expires, it is returned to the car insurance company 200 or erased or discarded by the driver 100 according to a contract between the driver 100 and the car insurance company 200.

The operation unit 15 is used for inputting a vehicle body number or setting a destination for executing route guidance, and is realized by a remote controller, a touch panel, or the like. The display 16 is used to display map information (current position information) at the time of route guidance or to display drinking information based on the detection result of the detection unit 11.

The control unit 20 includes a device identification information storage unit 21, a date and time information acquisition unit 22, a positioning calculation unit 23, a vehicle identification information acquisition unit 24, an encryption unit 25, a recording unit 26, and a display control unit 27.

The device identification information storage unit 21 stores a device ID for identifying the navigation device 10 and is realized by a nonvolatile memory. Note that information uniquely assigned to each navigation device 10 such as a product number may be used as the device ID.

The date information acquisition unit 22 acquires date information received by the GPS receiver 12. Note that date and time information measured by RTC (Real Time Clock) may be acquired instead of reception by the GPS receiver 12.

In addition to the date and time information received by the GPS receiver 12 and the map information read from the map information database 13, the positioning calculation unit 23 detects detection results of unillustrated self-contained navigation sensors (angle sensor and distance sensor), vehicle speed pulses, and the like. Based on the above, the current position of the vehicle 1 is measured. Current position information indicating the current position measured by the positioning calculation unit 23 is recorded in the memory M together with drinking information. The current position information may indicate latitude, longitude, altitude, or may indicate an address or map code.

The vehicle identification information acquisition unit 24 acquires the vehicle body number input by the operation unit 15 as vehicle identification information. The acquired vehicle body number is stored in a nonvolatile memory (not shown). As vehicle identification information, a vehicle code uniquely assigned to each vehicle 1 by each automobile manufacturer may be used instead of the vehicle body number. Further, the vehicle code may be read from the control device of the vehicle 1.

The encryption unit 25 encrypts various types of information using the encryption key registered in the memory M. The information to be encrypted is the drinking information, device ID, date / time information, current position information, and body number. These pieces of information are acquired (read) in accordance with the detection timing of the detection unit 11, and all the information is collectively encrypted.

The recording unit 26 records the information encrypted by the encryption unit 25 in the memory M. When the memory M is a rewritable recording medium and the capacity is small (when all information during the insurance contract period cannot be recorded), the recording unit 26 records new information while deleting old information in order. It is preferable to continue.

The display control unit 27 performs display control of the display 16 and displays drinking information on the display 16 in accordance with a drinking information display command from the operation unit 15. FIG. 3 is a diagram showing an example of the display. As shown in the figure, as drinking information, information (seat name) indicating each seat (arrangement of each alcohol sensor AS1 to AS4) and detection results of alcohol sensors AS1 to AS4 arranged in each seat correspond to each other. To display. As the detection results of the alcohol sensors AS1 to AS4, the alcohol concentration in the expiration is numerically displayed (see reference numeral 71). Further, it is determined whether or not the alcohol concentration in the driver's breath exceeds a predetermined value. If the concentration exceeds the predetermined value (for example, if the alcohol concentration in the breath is 0.12 mg / l or more, the drinking amount determination unit ) Displays a warning (see reference numeral 72). Moreover, the detection date information (based on the date information acquired by the date information acquisition unit 22) indicating the detection date is displayed together with the display of drinking information (see reference numeral 73).

In addition, when the alcohol concentration in the expiration of the driver's seat exceeds a predetermined value, a notification may be given to the outside of the vehicle 1 (to the outside of the vehicle using an external notification unit mounted on the vehicle 1). Notification). As a specific example of the external notification unit, for example, a hazard lamp or a light attached to the outside of the vehicle can be considered, and notification is performed by outputting a notification signal (output unit) to these. As a notification mode, a method such as turning on a hazard lamp or blinking a light attached to the outside of the vehicle can be considered. According to this configuration, when the driver 100 is in a drunk state, it is possible to notify the surrounding vehicle 1 that it is in a dangerous state, and thus the risk of an accident can be reduced. Further, even when an emergency situation arises in which a person has to drive even though he / she is in a drunk state, the surrounding vehicle 1 can be alerted.

Next, the recording process of the navigation device 10 will be described with reference to FIG. The navigation device 10 (control unit 20) detects the alcohol concentration by the alcohol sensors AS1 to AS4 (detection unit 11) with the engine start (running start) as a trigger (S01). Subsequently, the drinking information as detection results of the alcohol sensors AS1 to AS4, the device ID read from the device identification information storage unit 21, the date / time information acquired by the date / time information acquisition unit 22, and the current result based on the positioning result of the positioning calculation unit 23 The vehicle body number acquired by the position information and vehicle identification information acquisition unit 24 is acquired (S02 to S06). Note that S02 to S06 are in no particular order.

Subsequently, the acquired information is encrypted by the encryption unit 25 (S07), and the encrypted information is recorded in the memory M by the recording unit 26 (S08). Thereafter, it is determined whether or not the engine is stopped (S09). If the engine is stopped (S09: Yes), the recording process is terminated. If the engine is not stopped (S09: No), it is determined whether or not a predetermined time has elapsed since the previous detection (S10). If the predetermined time has elapsed (S10: Yes), the processes after S01 are repeated. .

Next, the flow of the insurance contract will be described with reference to FIG. 5 and FIG. FIG. 5 is a diagram illustrating a hardware configuration of the insurance contract processing system SY. Here, a client terminal 110 owned (managed) by the driver 100, an insurance management server 210 operated and managed by the car insurance company 200, and a network NT such as the Internet connecting them are shown.

The client terminal 110 is configured by a general personal computer, and includes a computer main body 111, a display 112, a keyboard 113, and the like. The insurance management server 210 is connected to a memory recording device 212 for registering an encryption key in the memory M and a printer 213 for printing an insurance contract.

FIG. 6 is a flowchart showing the insurance contract procedure. The client terminal 110 first inputs the current insurance contract information using an input device such as the keyboard 113 on a contract information input screen (not shown) provided as a Web page by the insurance management server 210 (S21). As current insurance contract information, information such as whether car insurance has been taken, the number of contracts, and the maturity date are entered. Subsequently, the client terminal 110 inputs vehicle information (S22). As vehicle information, information on vehicle verification information (body number, model, vehicle type, manufacturer, vehicle name, date of first year registration, etc.) and equipment related to insurance premiums (ABS, airbag, immobilizer, etc.) is input.

Subsequently, the client terminal 110 inputs driver information (S23). As the driver information, the storage location of the vehicle 1, the purpose of use, the color of the license, the age, and the like are input. Further, the client terminal 110 inputs an insurance plan (S24). As the insurance plan, the necessity of vehicle insurance, interpersonal compensation, objective compensation, personal injury, etc. are entered. Furthermore, when the target device (the navigation device 10 of the present embodiment) is attached to the vehicle 1 to be contracted (S25: Yes), the client terminal 110 inputs device information (S26). As device information, the model name, device ID, etc. of the navigation device 10 are input. Note that the information input in S21 to S26 is in no particular order.

When the device information is input, the insurance management server 210 generates an encryption key (S27) and registers it in the memory M by the memory recording device 212 (S28). This encryption key is a unique code generated based on the insurance company code, contract number, and the like. Further, the automobile insurance premium is calculated based on the input information in S21 to S26 (S29). Here, when the device information is input (S25: Yes), the insurance premium is discounted as compared to the case (S25: No).

Thereafter, the insurance management server 210 generates an insurance contract and saves it in a database (not shown) (S30), prints the insurance contract with the printer 213 (S31), and ends the process. The memory M in which the encryption key is registered and the printed insurance contract are mailed to the driver 100. The driver 100 installs the memory M in the navigation device 10 within a predetermined period to prepare for the occurrence of an accident. If an accident occurs and the memory M is not installed in the navigation device 10, it is determined that the contract is not fulfilled, and the guarantee by the car insurance company 200 is not applied.

As mentioned above, according to the navigation apparatus 10 of 1st Embodiment, since the drinking information which is the detection result of the detection part 11 is recorded on the memory M, it can prove the drinking state (at least in the car) at the time of an accident occurrence. it can. In addition, as the drinking information, since the detection results of the alcohol sensors AS1 to AS4 arranged in each seat are recorded, the drinking state of the passenger sitting in each seat can be specified. Thereby, for example, when the driver 100 is drunk, when the accident occurs, it cannot be said that the person has not drunk, and this is useful for the verification of drunk driving by a third party such as the car insurance company 200 or the police. be able to. In addition, when the driver 100 is not drinking, there is no problem that the driver 100 can deny the drunk driving, and the dangerous driving lethal injury is accidentally applied.

In addition, since recording of drinking information and the like is periodically performed while the vehicle 1 is traveling, the driver 100 is not bothered. That is, the driver 100 can prove that he / she was not in a drunk state at the time of an accident or the like, with the trouble of simply installing the memory M in the navigation device 10.

In addition, since the device ID, date / time information, current position information, and body number are recorded in the memory M together with the drinking information, it is recorded by the navigation device 10 that is surely reported by the third party at the time of the insurance contract. Whether it was recorded within the contract period, coincides with the reported accident location (accident location where the accident proof has been received), or is the accident caused by the vehicle 1 covered by the insurance contract, Etc. can be analyzed.

In addition, since the various types of information are encrypted and recorded, it is possible to prevent an illegal act such as the driver 100 intentionally rewriting the information. Thereby, the credibility of drinking information can be improved, and the value as evidence of the drinking information can be increased.

In addition, since the drinking information is displayed on the display 16, the driver 100 and other passengers can grasp their drinking state. Further, since the warning is given when the driver 100 is in a drunk state, drunk driving can be prevented in advance.

In the above embodiment, the alcohol sensors AS1 to AS4 are arranged for each seat, but may be arranged for each seat. In other words, in the case of a four-seater passenger car, alcohol sensors may be arranged at three locations of a driver seat, a passenger seat, and a rear seat.

In the above embodiment, the encryption key is a unique code generated based on the insurance company code, contract number, etc., but an alphanumeric string randomly drawn for each contract may be used. good. Also, instead of generating different encryption keys for each insurance contract, a uniform public key may be used by the car insurance company 200. In this case, S27 and S28 can be omitted in the flowchart of FIG. 6, and the memory M in which the public key is registered in advance is sent to the driver 100 (insurance policyholder).

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the above embodiment, the plurality of alcohol sensors AS1 to AS4 are arranged for each seat. However, the present embodiment is different in that the alcohol sensors AS1 to AS4 are distributed inside the vehicle regardless of the seat. In the above embodiment, the drinking information or the like is recorded in the memory M, but in the present embodiment, it is transmitted to the external server 50 (external device). Hereinafter, a description will be given focusing on differences from the first embodiment.

FIG. 7 is a functional block diagram of the navigation device 10 according to the present embodiment. The detection unit 30 according to the present embodiment includes three alcohol sensors AS11 to AS13, which are arranged at the front right side, the front left side, and the rear center of the vehicle interior, respectively. It should be noted that the alcohol sensors AS11 to AS13 of the present embodiment have a higher degree of freedom than the alcohol sensors AS1 to AS4 of the first embodiment, such as the vehicle ceiling, seat seat (headrest), and lower seat. it can.

Also, the control unit 20 of the present embodiment is newly provided with a drinking level calculation unit 31. The drinking level calculation unit 31 calculates the drinking level of the passenger on each seat based on the detection results of the alcohol sensors AS11 to AS13 and the arrangement of the alcohol sensors AS11 to AS13. In the present embodiment, the “drinking level” is expressed in four stages of “no drinking”, “low concentration”, “medium concentration”, and “high concentration” for each seat.

Also, the encryption unit 32 encrypts the drinking level of the passenger of each seat seat calculated by the drinking level calculation unit 31 as drinking information. In addition, the point which encrypts apparatus ID, date information, current position information, and a vehicle body number with drinking information is the same as that of 1st Embodiment. An encryption key for encryption is input by the operation unit 15. As the encryption key, the alphanumeric string notified in the insurance contract (the encryption key generated in S27 in FIG. 6) is input. That is, in the present embodiment, compared with the first embodiment (hardware configuration shown in FIG. 5), the memory recording device 212 is not necessary, and instead of the encryption key to the insurance contract by the printer 213, Printing is required.

In addition, the recording transmission unit 33 (recording unit) transmits the information encrypted by the encryption unit 32 to the external server 50. The transmission timing may be every detection by the detection unit 30, may be executed at a predetermined time such as once a day, or when the navigation device 10 is activated (when the engine of the vehicle 1 is started). It may be a predetermined timing.

The external server 50 is operated and managed by the car insurance company 200 and can be used together with the insurance management server 210 shown in the first embodiment. In addition, the external server 50 includes a drinking information database 60 that stores recording data transmitted from the navigation apparatus 10 that has an insurance contract.

On the other hand, the display control unit 34 displays the detection result of the detection unit 30 and the drinking level for each seat on the display 16 as drinking information. FIG. 8 is a diagram illustrating a display example of drinking information according to the present embodiment. As shown in the figure, in this embodiment, the detection results (see reference numeral 81) of the alcohol sensors AS11 to AS13 and the seats obtained from the detection results (driver's seat, front passenger seat, rear left seat, rear right seat) (Seat) drinking level (see reference numeral 82). The drinking level is obtained by a predetermined algorithm using the detection results (alcohol concentration in breath) of each alcohol sensor AS11 to AS13 and the arrangement information (information stored in advance) of each alcohol sensor AS11 to AS13 as parameters. Can do. For example, in the case of the example shown in FIG. 8, if the vehicle 1 is a right-hand drive vehicle, the detection result of the front right sensor AS11 closest to the driver's seat is 0.05 mg / l. Since the detection results of the alcohol sensors AS12 and AS13 indicate a high alcohol concentration, it is considered that the exhalation of a passenger other than the driver affected the front right sensor AS11. It is determined that there is no drinking. Note that, on the display 16, as with the first embodiment, the detection date and time information is also displayed together with the drinking information (see reference numeral 83).

As described above, according to the navigation device 10 of the second embodiment, the passengers of the respective seats calculated based on the arrangement of the plurality of alcohol sensors AS11 to AS13 distributed in the vehicle interior and the detection results thereof. Since the level of drinking is recorded, the drinking level of each passenger can be clearly identified. Moreover, since it is not necessary to arrange an alcohol sensor for each seat, the number of sensors can be reduced, and the cost of the navigation device 10 can be reduced.

Also, since drinking information and the like are transmitted to the external server 50, evidence maintenance can be performed even when the navigation device 10 is damaged due to an impact or fire at the time of the accident. Further, it is possible to prevent the user from intentionally erasing the recorded data that is disadvantageous to him. Furthermore, since the memory M is not required, the cost required for this can be reduced. In addition, since it is not necessary for the driver 100 to mail the memory M after the late occurrence, the car insurance company 200 can quickly determine whether or not the car insurance guarantee can be applied when an accident occurs. it can.

In the second embodiment, as the drinking information, the detection result by the detection unit 30 and the drinking level calculated based on the alcohol concentration in the breath as the detection result are displayed on the display 16. However, the blood alcohol concentration may be calculated and displayed based on the alcohol concentration in the breath. Furthermore, based on the alcohol concentration in expiration, “time required for alcohol disappearance (hereinafter referred to as“ alcohol disappearance time ”) may be calculated and displayed. In this case, the reference time may be displayed based on the reference weight (for example, 60 kg), and the seat seat and the weight of the passenger sitting on the seat seat are input by the operation unit 15. Thus, an accurate alcohol disappearance time of each passenger may be calculated. In this case, the weight of the driver 100 can be registered in advance, and an accurate alcohol disappearance time calculated based on the weight of the driver 100 can be calculated without requiring an input operation of the weight. Also good.

Further, as in the second embodiment, even when the alcohol sensors AS11 to AS13 are arranged regardless of the seat, the detection results themselves of the alcohol sensors AS11 to AS13 may be transmitted to the external server 50.

As described above, according to the navigation device 10 of the present invention, as described in the first embodiment and the second embodiment, the drinking information when the vehicle travels is recorded. Can prove. Moreover, since the information regarding the drinking level of each passenger in the vehicle is recorded as the drinking information, it is possible to reliably specify the drinking state of the driver 100 instead of the passenger.

In addition, although the case where the information recording device of the present invention was incorporated in the navigation device 10 was illustrated in the above embodiment, it may be realized by an electronic control unit (ECU: Engine Control Unit) that controls the vehicle 1. That is, each function in the control unit 20 of the navigation device 10 can be realized by an electronic control unit.

Further, in the above embodiment, it is described that the vehicle body number needs to be registered as the vehicle identification information before the start of use of the navigation device 10, but instead of the vehicle body number, an insurance contract with the car insurance company 200 is made. You may make it register a number. In addition, as vehicle identification information, if it is information which can identify the vehicle 1 in which the navigation apparatus 10 is mounted, the kind will not ask | require.

Further, along with the drinking information, information indicating “vehicle behavior” and information indicating “in-vehicle state” may be recorded. As “vehicle behavior”, by measuring “vehicle movement trajectory”, “speed change”, and “presence / absence of wobbling”, it can be used as an index as to whether or not the driver 100 is in a drunk state. In addition, the “state of the passenger compartment” can be used to determine the authenticity of drinking information by measuring passenger compartment information related to “presence of passengers”, “opening / closing of windows” and “setting of air conditioning equipment” in the passenger compartment. It can be. In other words, the presence or absence of passengers can be determined from the “presence / absence of passengers”, and the “opening / closing” and “setting of air conditioning equipment” from the “opening / closing of windows” and “setting of air conditioning equipment” can include opening the windows and taking in outside air by setting the air conditioning equipment. It can be determined whether or not camouflaging for reducing the detection accuracy of the alcohol sensor AS has been performed.

Information is stored together with the device ID. Hereinafter, these “drinking information” and “running information” are collectively referred to as “vehicle information”.

The communication unit 44 transmits the vehicle information read from the vehicle information storage unit 43 to the information management server 190 via the base station 89. Further, the map information database 13 stores map information necessary for the navigation device 10 to specify the current position and perform route guidance. The positioning calculation unit 23 measures the current position of the vehicle 1 based on the date and time information received by the GPS receiver 12, the map information read from the map information database 13, the detection result of the autonomous navigation sensor S1, and the like.

The display control unit 27 performs display control of the display 16. When the display control unit 27 displays the detection result of the alcohol sensor AS, the name of each seat is associated with the detection results (alcohol concentration in breath) of the alcohol sensors AS1 to AS4 arranged in each seat. indicate. Further, when the alcohol concentration in the breath at the driver's seat exceeds a predetermined value, a warning is displayed.

Next, the functional configuration of the insurance contract processing system SY1 will be described with reference to FIG. The navigation device 10 includes a drinking level detection unit 115, a traveling measurement unit 120, a drinking information storage unit 130, a traveling information storage unit 140, and a vehicle information transmission unit 150 as main functional configurations. The drinking information storage unit 130 and the travel information storage unit 140 correspond to the vehicle information storage unit 43 shown in FIG.

The drinking level detection unit 115 detects the drinking level of each passenger by a plurality of alcohol sensors AS arranged for each seat. The detection by the drinking level detection unit 115 is periodically performed every 10 minutes or every 30 minutes while the vehicle is running. In addition, the drinking information that is the detection result of the drinking level detection unit 115 is stored in the drinking information storage unit 130.

The travel measurement unit 120 measures the travel state of the vehicle 1, and travel information that is a measurement result is stored in the travel information storage unit 140. The measurement by the travel measurement unit 120 is always executed while the vehicle is traveling. As the “running state”, for example, various information displayed on the instrument panel such as a running speed and a running distance are measured. In addition, information related to vehicle behavior, such as the movement trajectory of the vehicle 1, speed change, and presence or absence of wobbling, is also measured. Here, the “vehicle movement trajectory” can be measured based on the coordinates (latitude, longitude, altitude) of the vehicle 1 obtained from the reception result of the GPS receiver 12, and “speed change” is measured by the acceleration sensor S 2. Measurement is possible based on the vehicle speed (acceleration, deceleration by braking) obtained from the detection result. Further, “presence / absence of wobbling” can be measured by detecting a white line on the road from the road surface image captured by the front camera FC and changing the distance between the white line and the vehicle 1 in the road width direction. The travel state measured by the travel measurement unit 120 is stored in the travel information storage unit 140 in association with the current position information obtained from the reception result of the GPS receiver 12.

The vehicle information transmission unit 150 reads the drinking information and the traveling information from the drinking information storage unit 130 and the traveling information storage unit 140, respectively, and transmits them as vehicle information to the information management server 190. At this time, the vehicle information is transmitted together with a device ID for identifying the navigation device 10. The vehicle information transmission unit 150 may transmit the vehicle information at regular intervals according to the detection timing of the drinking level detection unit 115, such as every 10 minutes or every 30 minutes, or may be transmitted by the driver 100. A predetermined operation or vehicle state such as when an instruction is given or when the engine is started / stopped may be used as a trigger.

Next, the functional configuration of the information management server 190 will be described. The information management server 190 includes a vehicle information receiving unit 510 and a vehicle information database DB. The vehicle information receiving unit 510 receives the vehicle information (and the device ID added thereto) transmitted from the vehicle information transmitting unit 150. Moreover, vehicle information database DB memorize | stores the said vehicle information with apparatus ID.

Next, the functional configuration of the insurance management server 210 will be described. The insurance management server 210 includes a calculation request entrusting unit 310, a vehicle information acquisition unit 320 (drinking information acquisition unit, travel information acquisition unit), a contract availability determination unit 330, an insurance premium calculation unit 340, and an insurance premium information transmission unit 350. ing.

The calculation request entrusting unit 310 receives a request for calculating the insurance premium for car insurance from the client terminal 110. The insurance premium calculation process by the insurance management server 210 is executed using the calculation request as a trigger. The vehicle information acquisition unit 320 acquires, from the information management server 190, vehicle information for a predetermined period of the navigation device 10 specified by the insurance fee calculation request from the client terminal 110. That is, the vehicle information for a predetermined period associated with the device ID input by the client terminal 110 at the time of the calculation request is acquired from the vehicle information database DB. In the present embodiment, vehicle information for about one year corresponding to the previous insurance contract period is acquired.

The contract availability determination unit 330 determines whether or not a car insurance contract is possible based on the acquired vehicle information in a predetermined period. Specifically, if a drinking history is detected more than a certain number of times from drinking information, or if a traffic violation (such as speeding violation or parking in a parking prohibited area) is detected more than a certain number of times from driving information, It is determined as “impossible”. The insurance premium calculation unit 340 calculates the insurance premium for automobile insurance when the contract determination unit 330 determines that the contract is “permitted”. The insurance premium is calculated based on a predetermined calculation algorithm, on the condition that the navigation device 10 is mounted on the vehicle 1, and a predetermined discount is performed. Further, when it is determined from the vehicle information that the driver is an excellent driver, the insurance premium is further discounted. In other words, the car insurance company 200 can attract many excellent drivers by giving a discount corresponding to a client with a low possibility of occurrence of an accident, and there are advantages for both the client and the client. The insurance premium information transmission unit 350 transmits insurance premium information, which is the calculation result of the insurance premium calculation unit 340, to the client terminal 110 that has received the calculation request.

Next, the functional configuration of the service server 180 will be described. The service server 180 includes a vehicle information acquisition unit 410, a vehicle cost calculation unit 420, an advice information generation unit 430, and an advice information transmission unit 440.

The vehicle information acquisition unit 410 acquires, from the information management server 190, vehicle information for a predetermined period from the navigation device 10 that has been requested for service when joining the insurance contract processing system SY1. In the present embodiment, vehicle information for the previous month transmitted from each navigation device 10 is acquired at the beginning of the month.

The vehicle cost calculation unit 420 calculates a vehicle cost that is necessary for maintenance and travel of the vehicle 1 for each navigation device 10 based on the acquired vehicle information in a predetermined period. Specifically, the total of the gasoline fee and toll road fee for a predetermined period is calculated. Expenses related to consumables such as oil change and tire change that can be calculated according to the travel distance or the like may be recorded as vehicle expenses.

The advice information generation unit 430 generates advice information for clients for each navigation device 10 based on vehicle information for a predetermined period (for the previous month). Note that as the “advice information”, based on the drinking information, a drinking history and a text document that prompts the user to stop drunk driving are generated. In addition, based on the driving information, the contents that point out the driving speed (especially those subject to speed violations), the timing when the brakes are pressed, the amount of wobbling, the number of breaks, etc. Generate a document. Furthermore, advice information related to the vehicle cost calculated by the vehicle cost calculation unit 420 is also generated. More specifically, a text document is generated that includes one month's worth of vehicle expenses, a breakdown thereof, and contents that guide eco-driving. The advice information can be generated by extracting a sentence example corresponding to the vehicle information from a plurality of types of sentence examples (templates) prepared in advance. The advice information transmission unit 440 transmits the advice information generated for each navigation device 10 to the client terminal 110 having the e-mail address registered at the time of joining the insurance contract processing system SY1.

Finally, the functional configuration of the client terminal 110 will be described. The client terminal 110 includes a calculation request transmission unit 211, an insurance premium information reception unit 220, an advice information reception unit 230, and a display unit 240.

The calculation request transmission unit 211 requests the insurance management server 210 to calculate an insurance premium. At the time of the calculation request, it is necessary to declare the device ID of the navigation device 10 and the e-mail address of itself (client terminal 110). The insurance premium information receiving unit 220 receives the insurance premium information transmitted from the insurance premium information transmitting unit 350 of the insurance management server 210. The advice information receiving unit 230 receives the advice information transmitted from the advice information transmitting unit 440 of the service server 180. The display unit 240 displays the received insurance premium information and advice information on a display screen provided in the client terminal 110.

Next, the flow of insurance premium estimation processing by the insurance contract processing system SY1 will be described with reference to the flowchart of FIG. The navigation apparatus 10 subscribing to the insurance contract processing system SY1 detects the drinking level for each passenger in each of the mounted vehicles 1 (S51). Further, during traveling, the traveling state is measured based on the detection results of the GPS receiver 12, various sensors S1, S2, etc. (see FIG. 10) (S52). The navigation device 10 transmits the drinking information that is the detection result of the drinking level and the driving information that is the measurement result of the driving state to the information management server 190 as vehicle information at a predetermined timing (S53). The information management server 190 stores the vehicle information received from each navigation device 10 in the vehicle information database DB together with the device ID of each navigation device 10.

On the other hand, the client terminal 110 makes an insurance premium calculation request (quotation request) before the expiration of the insurance period (S54). In this step, the contents of the insurance contract are input to a contract information input screen (not shown) provided as a Web page by the insurance management server 210 using an input device such as a keyboard. Specifically, the current contract information, vehicle information, driver information, insurance plan, etc. are input. Further, the client terminal 110 inputs the device ID of the navigation device 10 to be contracted and its own e-mail address to which the insurance fee information is transmitted.

When the insurance management server 210 receives an insurance premium calculation request from the client terminal 110, the insurance management server 210 acquires vehicle information within the previous insurance period from the vehicle information database DB (S55), and determines whether or not a contract is possible (S56). If it is determined that the contract is “permitted”, the insurance premium is calculated (S57), and the insurance premium information that is the calculation result is transmitted to the client terminal 110 (S58). If it is determined in S56 that the contract is “impossible”, the client terminal 110 is notified accordingly.

When the client terminal 110 acquires the premium information from the insurance management server 210 (S59), it displays it on the display screen (S60). The client confirms the insurance premium information (estimated result) on the display screen, and when he / she wants an insurance contract, he accesses the insurance management server 210 again to make a contract.

Next, the flow of advice information provision processing by the insurance contract processing system SY1 will be described with reference to the flowchart of FIG. The processing of S71 to S73 of the navigation device 10 is the same as S51 to S53 shown in FIG. The service server 180 acquires vehicle information for the previous month from the vehicle information database DB (S75) at a predetermined time at the beginning of the month every month (S75), and based on the vehicle information for the previous month. The vehicle cost is calculated (S76). Further, advice information is generated based on the acquired vehicle information and the calculated vehicle cost (S77), and the advice information is transmitted to the client terminal 110 (S78).

When the client terminal 110 acquires the advice information from the service server 180 (S79), it displays it on the display screen (S80). In the above example, the client terminal 110 acquires the advice information at the beginning of the month every month, but the acquisition interval of the advice information may be specified from the client terminal 110. For example, when the acquisition interval is designated as 6 months, the service server 180 acquires vehicle information for the immediately preceding 6 months from the vehicle information database DB every 6 months, and generates advice information.

As described above, according to the insurance contract processing system SY1 of the present embodiment, the insurance management server 210 calculates the insurance premium based on the vehicle information in the predetermined period acquired from the information management server 190. I want an insurance contract, such as increasing the premium for 100 or a driver 100 who has a traffic violation history, or reducing the premium for a driver 100 who has no drinking history or a driver 100 who performs safe driving It is possible to calculate an appropriate automobile insurance premium according to the contract applicant. Moreover, since the navigation apparatus 10 transmits drinking information to the information management server 190, vehicle information will be lost even if the navigation apparatus 10 is damaged due to an impact or fire at the time of an accident. There is nothing. In addition, it is possible to prevent the client from intentionally erasing the recorded data that is disadvantageous to the client.

In addition, since the drinking level detection unit 115 of the navigation device 10 detects the drinking level of each passenger by using a plurality of alcohol sensors AS arranged for each seat in the passenger compartment, the drinking level of the driver 100 is not the passenger. The state can be specified. As a result, even if there is a complaint such as “the detection result of the alcohol sensor was due to the passenger's drinking and an unreasonable insurance premium was claimed,” vehicle information (drinking information) as credible evidence Can be presented.

Further, since the service server 180 provides advice information on driving attention and improvement measures based on the vehicle information in a predetermined period acquired from the information management server 190, the service server 180 can be used for safe driving of the driver 100. Further, since the service server 180 also provides advice information based on the vehicle cost calculated from the travel information, the client can help reduce the vehicle cost.

In the above embodiment, the vehicle information is periodically transmitted from the navigation device 10 to the information management server 190. However, from any one of the insurance management server 210, the service server 180, and the information management server 190, A transmission request may be issued at an arbitrary timing, and the navigation device 10 may read the vehicle information from the vehicle information storage unit 43 and transmit it to the information management server 190 in response thereto.

In the above embodiment, the insurance contract processing system SY1 is configured by the navigation device 10, the client terminal 110, the insurance management server 210, the service server 180, and the information management server 190, but the client terminal 110 is omitted. The navigation device 10 may have the function of the client terminal 110. According to this configuration, it is possible to easily request a premium calculation or receive insurance premium information from the navigation device 10.

Further, the information management server 190 may be omitted from the configuration of the insurance contract processing system SY1 shown in the above embodiment, and the function of the information management server 190 may be provided in the insurance management server 210 and / or the service server 180. In this case, the navigation device 10 transmits vehicle information to both

servers

210 and 180. According to this configuration, since the information management server 190 is not necessary, the construction cost of the insurance contract processing system SY1 can be reduced.

Further, as a system form using the information management server 190 shown in the above embodiment, a form in which vehicle information is provided to an automobile manufacturer, a car purchase company, a road public corporation, or the like can be considered. For example, an automobile manufacturer or a car purchase company may prompt the user to replace the vehicle 1 whose travel distance has reached a predetermined distance based on travel information. The public corporation may increase or discount the ETC (Electronic Toll Collection System) fee according to the speed compliance rate of highways and the like.

[Third Embodiment]
Next, a fourth embodiment of the present invention will be described with reference to FIGS. 14 and 15. In the third embodiment, vehicle information is transmitted from the navigation device 10 to the information management server 190. However, the present embodiment is different in that the vehicle information is recorded in the memory M. The memory M is read by an insurance premium calculation device 70 managed by the automobile insurance company 200, and the insurance premium of the automobile insurance is calculated. Hereinafter, a description will be given focusing on differences from the first embodiment.

FIG. 14 is a system configuration diagram of the insurance contract processing system SY2 according to the present embodiment. The insurance contract processing system SY2 includes a navigation device 10, a memory M that can be attached to and detached from the navigation device 10, and an insurance fee calculation device 70 that calculates an insurance fee for automobile insurance. The insurance fee calculation device 70 is connected to a memory reading device 78 for reading vehicle information from the memory M and a printer 79 for printing an estimate.

Compared with the device configuration of the navigation device 10 shown in FIG. 10, the device configuration of the navigation device 10 eliminates the need for the communication unit 44, and reads / writes data from / to the memory mounting unit for mounting the memory M. A memory controller to be performed (both not shown) is added.

As described above, the memory M is used to record vehicle information and calculate a premium for automobile insurance for the next year. The memory M is attached for a period corresponding to an insurance contract period (for example, one year) to prove that the driver 100 was in a drunk state or not in a drunk state at the time of an accident. Is also used. In other words, if the vehicle 1 in which the navigation device 10 is mounted has an accident and the memory M is not installed in the navigation device 10, it is determined that the contract is not fulfilled, and the guarantee by the car insurance company 200 is applied. Not. The medium of the memory M may be either rewritable or non-rewritable. The former recording medium can be reused depending on the format, and resource saving can be achieved. In addition, since the latter recording medium can prevent unauthorized rewriting of information, the credibility as evidence when a traffic accident occurs can be improved. When the insurance contract period expires, it is returned to the car insurance company 200 or deleted or discarded by the driver 100 according to a contract between the driver 100 and the car insurance company 200.

The insurance fee calculation device 70 is installed in an automobile manufacturer, a car accessory store, or the like with which the automobile insurance company 200 is affiliated. The vehicle information is read from the memory M presented by the client by the memory reading device 78, and the vehicle Insurance premiums are calculated based on the information. The calculated insurance premium is printed by the printer 79 as an estimate.

Next, with reference to the flowchart of FIG. 15, the insurance fee estimation processing by the insurance fee calculating apparatus 70 will be described. The insurance fee calculation device 70 reads vehicle information from the memory M (S91), and checks whether or not a predetermined period (for example, from the start date of the previous insurance contract period to the estimate calculation date) is recorded. It discriminate | determines (S92). Here, when recording for a predetermined period is performed (S92: Yes), it is determined whether or not an insurance contract is possible based on the contents of the vehicle information (S93). Whether or not the contract is acceptable is determined based on the same criteria as the contract availability determination unit 330 shown in FIG.

If it is determined in S53 that the contract is “permitted” (S93: Yes), an insurance premium is calculated based on the read vehicle information (S94), and an estimate including the insurance premium information as the calculation result is provided. It is created (S95) and printed by the printer 79 (S96). On the other hand, when recording for a predetermined period is not performed in the memory M (S92: No), and when it is determined that the contract is “impossible” (S93: No), it is impossible to estimate without creating an estimate. A notice to the effect is printed.

As described above, according to the present embodiment, the insurance fee calculation device 70 that does not require a network environment reads the vehicle information for a predetermined period from the memory M and calculates the insurance fee for automobile insurance.
